Deep Continuous Contour Trenches

Uses:-

1. To reduce the speed of rainwater flowing rapidly on the mountain tops.

2. To reduce soil erosion.

3. To absorb the flowing water as much as possible into the soil.

4. To make wasteland productive and to bring this area under irrigation to some extent.

5. To develop wasteland and degraded land that is suitable for treatment effectively and rapidly.

 

Area Selection:-

• This treatment is done on 0 to 8% slope. 
•  This treatment is usually done at the top or bottom of the hill.

Technical Measurement:-

• We can make 240 m. long Deep CCT per hectare.
•  Length of the trench = 20 m.
•  Width of the trench = 1 m.
•  Depth of the trench = 1 m./1.5 m.
•  The distance between two rows of Deep CCT should be 33 m.
•  The distance between the two trenches of Deep CCT should be 2 m.
•  The bund should be 1 m. high, leaving a distance of 30 cm below the trench. Also, the length of the bund should be equal to the length of the trench.
•  Pitching of stones should be done on both sides of the bund.
